What is Compaction?

Soil compaction is defined as the method of mechanically increasing the density of soil.

How do I measure Compaction, and does this compare to the compaction readings on the Machine?

Trimble Compaction Control Systems

Measures soil stiffness as an indication of soil compaction

Displays compaction measurements, pass counts, provides guidance to the operator

Maps and records compaction data

Conventional Compaction MeasurementsNuclear Moisture-Density Drive Core Plate Load Test

Clegg Impact & Portable FWD GeoGauge Dynamic Cone Penetrometer

Quality Assurance / Quality Control

Limitations of Nuclear Densometer and other traditional methods– Difficult to administer in a large work area– Greater visual inspection required on behalf of the

Geotechnical Consultant (more labor)– Potential problem areas go unidentified even

though they appear to be fine Unstable sub-grade Moisture level above or below optimum Over compaction

– Expensive repairs at a later date with premature surface failures

Compaction Terms CMV

– Compaction Meter Value– A measure of soil stiffness used as an indication of

compaction. Target CMV

– Desired CMV value set on the compactor Target CMV range

– Range of CMV value above and below target CMV deemed to be acceptable (default SVO/GCS900 values 80-130% of target)

Target Thickness – Maximum desired material thickness

Decoupled– Drum is not in contact with the soil, based on RMV

Amplitude, Frequency and RMV (Resonance Meter Value)– Values associated with vibratory compactors

Proofing Run– Verification pass over a completed layer, normally checked

with conventional compaction tests. Typically performed every nth layer in the construction process.

Compaction Reporting Module

Target customers– Site Engineer & Project Manager– Clients (DOTs)– Contractors instructed to use this technology by

clients in project specifications This module provides

– A high level summary view to quickly quantify large areas and multiple layers of compaction data

– Tools to view detailed pass by pass progress in areas of interest, including all the compaction data, not just a proofing pass

The customer gain is – Improved detection of potential problems– Better utilization of machinery– Verification that target criteria have been met

Trimble CCS900 – why compaction control?

More efficient compaction operations– The right number of passes (No more, no less)– Reduced fuel, labor and machine costs

Early detection of “soft” spots– Prior to importing material &

during fill operations– Fix it before it becomes a problem

More consistent compaction results– Higher pass rates on inspections– Equals less re-work

Archival of data – For warranty documentation– Evidence of good practice– Strong defense if there is a future problem
